Fatal Error - Random Loans Checkbox

Whenever I check the Random Loans box I get an error like the following:

Fatal error: Cannot use object of type stdClass as array in /home/www/example.com/htdocs/sites/all/modules/kiva/kiva.module on line 134

It looks like if I change line 90 to:
$loans[] = $json->loans[$key];

from:
$loans = $json->loans[$key];

it will build the array and the error message goes away.
